[0037] In order to fully understand the purpose, features and effects of the present invention, the concept, specific structure and technical effects of the present invention will be further described below with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figure 1 to Figure 2 As shown, a lifting suspension system comprises:

[0040] The front wheel lifting mechanism 110, the rear wheel lifting mechanism 120, the front lifting solenoid valve 130, the rear lifting solenoid valve 140, the air pump 190, and the control mechanism 150, wherein:

[0041] The front lift solenoid valve 130 is connected to the front wheel lift mechanism 110 and the rear wheel lift mechanism 120, and the front lift solenoid valve 130 is also electrically connected to the control mechanism 150, so as to control the front wheel lift mechanism and the rear wheel lift mechanism to perform a lift action when receiving a lift signal from the control mechanism;

[0042] The rear lift solenoid valve 140 is connected to the rear wheel lifting mechanism 120, and is also electrically connected to the control mechanism 150, so as to control the rear wheel lifting mechanism to perform a lifting action when receiving a rear wheel lifting signal sent by the control mechanism.

[0043] The lifting suspension system adopts the above structure, which controls the front lifting solenoid valve through the control mechanism, so that the front wheel lifting mechanism and the rear wheel lifting mechanism are lifted, thereby realizing the lifting of the vehicle chassis; it controls the rear lifting solenoid valve through the control mechanism, so that the rear wheel lifting mechanism is lifted, thereby realizing the separate lifting of the rear wheel, so that the motorcycle has a better driving experience when traveling on a sloping road surface.

[0044] Further, the front lift solenoid valve 130 has a front lift air inlet end and a front lift air outlet end, the front lift air inlet end is connected to the air pump, the front lift air outlet end is connected to the front wheel lifting mechanism, and the front lift air outlet end is also connected to the rear wheel lifting mechanism;

[0045] When the front lift solenoid valve receives the lifting signal from the control mechanism, the front lift solenoid valve connects the front lift air inlet and the front lift air outlet, and the front wheel lifting mechanism and the rear wheel mechanism cylinder perform lifting action. The control mechanism controls the power on or off of the front lift solenoid valve to control the connection between the front lift air inlet and the front lift air outlet, so that the air pump supplies air to the front wheel lifting cylinder in the front wheel lifting mechanism and the rear wheel lifting cylinder in the rear wheel lifting mechanism, so that the front wheel lifting cylinder and the rear wheel lifting cylinder perform synchronous extension action, thereby realizing the lifting of the vehicle chassis.

[0046] Further, the rear lift solenoid valve 140 has a rear lift air inlet end and a rear lift air outlet end, the rear lift air inlet end is connected to the air pump, and the rear lift air outlet end is connected to the rear wheel lifting mechanism;

[0047] When the rear lift solenoid valve receives the rear wheel lifting signal from the control mechanism, the rear lift solenoid valve connects the rear lift air inlet and the rear lift air outlet, and the rear wheel lifting mechanism performs a lifting action. The control mechanism controls the power on or off of the rear lift solenoid valve to control the connection between the rear front lift air inlet and the rear lift air outlet, so that the air pump supplies air to the rear wheel lifting cylinder in the rear wheel lifting mechanism, so that the rear wheel lifting cylinder performs an extension action, thereby realizing the independent lifting of the rear wheel.

[0048] Specifically, a one-way air valve is provided between the front rising air outlet and the rear wheel lifting mechanism, and the gas flow direction of the one-way air valve is the direction in which the gas flows from the front rising air outlet to the rear wheel lifting mechanism.

[0049] Furthermore, the lifting suspension system also includes a descending solenoid valve, the descending solenoid valve having a descending air inlet end and a descending air outlet end, the descending air outlet end is connected to the atmospheric environment, and the descending air inlet end is connected to the rear wheel lifting mechanism;

[0050] The descending solenoid valve is electrically connected to the control mechanism, and is used to control the front wheel lifting mechanism and the rear wheel lifting mechanism to perform a descending action when receiving a descending signal from the control mechanism. In the above manner, when the descending solenoid valve is working, the descending air inlet end is connected to the descending air outlet end, and the rear wheel lifting cylinder is deflated to lower the rear wheel that is raised alone, or the rear wheel lifting cylinder and the front wheel lifting cylinder are deflated to lower the front wheel and the rear wheel, and the vehicle chassis is lowered.

[0051] Furthermore, the lifting suspension system also includes a high-pass pressure switch 180, which is connected to the rear wheel lifting mechanism to obtain a parking frame release signal or a parking frame retracting signal according to the gas pressure in the rear wheel lifting mechanism.

[0052] Furthermore, the lifting suspension system also includes a linkage solenoid valve, a parking frame driving mechanism and a parking frame drivingly connected to the control cylinder;

[0053] The linkage solenoid valve is electrically connected to the high-pass pressure switch, and is used to control the parking frame drive mechanism to release the parking frame when receiving a parking frame release signal from the high-pass pressure switch, or to control the parking frame drive mechanism to retract the parking frame when receiving a parking frame retraction signal from the high-pass pressure switch.

[0054] Specifically, when there is gas in the pipeline of the rear wheel lifting mechanism, that is, the motorcycle enters a raised state and is ready to drive at any time, the high-pass pressure switch generates a parking rack folding signal to control the parking rack drive mechanism to fold the parking rack, so that the driver does not need to manually fold the parking rack; when there is no gas in the pipeline of the rear wheel lifting mechanism, that is, the motorcycle enters a lowered state and is ready to park, the high-pass pressure switch generates a parking rack release signal to control the parking rack drive mechanism to release the parking rack, so that the driver does not need to manually fold the parking rack, which is convenient for use and prevents the motorcycle chassis from directly colliding with the ground when the parking rack is forgotten to be released.

[0055] Preferably, the parking frame driving mechanism is a horizontal telescopic cylinder.

[0056] Further, the front wheel lifting mechanism comprises a front wheel lifting cylinder and a first multi-pipe distributor connected to the front wheel lifting cylinder;

[0057] The rear wheel lifting mechanism comprises a rear wheel lifting cylinder and a second multi-pipe distributor connected to the rear wheel lifting cylinder.

[0058] Regarding the wiring method of the lifting suspension system of the present invention, the following method can be adopted: the first interface of the first multi-channel distributor is connected to the air pump, the second interface of the first multi-channel distributor is connected to the front lifting air intake end of the front lifting solenoid valve, the front lifting air outlet end is connected to the front wheel lifting cylinder, and is also connected to the air intake end of the one-way air valve, and the third interface of the first multi-channel distributor is connected to the rear lifting air intake end of the rear lifting solenoid valve; the first interface of the second multi-channel distributor is connected to the rear lifting air outlet end of the rear lifting solenoid valve, the second interface is connected to the air outlet end of the one-way air valve, the third interface is connected to the descending air intake end of the descending solenoid valve, the fourth interface is connected to the rear wheel lifting cylinder, the fifth interface is connected to the high-pass pressure switch, and the sixth interface is connected to the air intake end of the linkage solenoid valve.

[0059] After the wiring is completed, when the motorcycle chassis needs to be raised as a whole, the front lifting solenoid valve is opened, and the rear lifting solenoid valve and the lowering solenoid valve are closed. At this time, the gas from the air pump enters the first multi-channel distributor and supplies air to the front wheel lifting cylinder through the second interface, and enters the second multi-channel distributor through the one-way air valve, and then supplies air to the rear wheel lifting cylinder;

[0060] When the rear wheel needs to be raised separately, the rear lifting solenoid valve is opened, and the front lifting solenoid valve and the lowering solenoid valve are closed. At this time, the gas from the air pump enters the first multi-channel distributor and enters the second multi-channel distributor through the third interface, and then supplies gas to the rear wheel lifting cylinder. At this time, since the second interface of the second multi-channel distributor is connected to the gas outlet end of the one-way gas valve, the gas cannot be supplied to the front wheel lifting cylinder, thereby achieving the rear wheel lifting separately;

[0061] When the vehicle chassis needs to be lowered, the front lifting solenoid valve and the rear lifting solenoid valve are closed, the lowering solenoid valve is opened, and the gas in the first multi-pipe distributor and the second multi-pipe distributor, the front wheel lifting cylinder and the rear wheel lifting cylinder will be discharged.

[0062] Example 2

[0063] like Figure 3 As shown, the technical solutions of this embodiment are basically the same as those of embodiment 1, and the main difference lies in that: further, the lifting suspension system also includes a delay circuit, which is electrically connected to the high-pass pressure switch and the linkage solenoid valve.

[0064] When the front wheel lifting cylinder and the rear wheel lifting cylinder are supplied with air, although the air pressure is high, when the cylinder is not fully extended, the air pressure will be unstable, which may cause the high-pass pressure switch to generate a parking frame release signal or a parking frame retracting signal in a certain period of time, causing the parking frame to switch back and forth between the released state and the retracted state. The lifting suspension system of the present invention inputs the signal generated by the high-pass pressure switch into the delay circuit, and outputs the parking frame release signal after the delay circuit checks whether the air pressure is stable, thereby preventing the parking frame from switching back and forth between the released state and the retracted state.

[0065] It should be noted that the delay circuit involved in the present invention may use a delay circuit known in the art, and the present invention is not limited to this.

[0066] The present invention also provides a motorcycle, which comprises the lifting suspension system described above.
